It is concluded that the growth of thickness of these layers is primarily caused by the spread of the beam energy density from pulse to pulse and by the presence of individual pulses with a higher-than-average value of energy density.
      
It is shown that a radial SPS does not ensure satisfactory reproducibility of the plasma flow parameters from pulse to pulse, which influences the operation stability of plasma opening switches.
      
In particular, we show that the profile variations from pulse to pulse are not reduced to a simple modulation of the accretion rate specified by external conditions.

As a rectangular pulse is applied to a Capacity Loaded Cathode Follower operated under nonlinear condition, the falling edge of the output pulse is engthened. This article analyses the physical processes of the lengthening phenomena both for positive and negative pulses. Theoretical approach to obtain such a falling curve is suggested, and checked by experimental results.

本文叙述一个用来检验核物理中电子学仪器的脈冲发生器的线路。这个脈冲发生器可以产生单个的或成双的矩形脈冲。除了矩形脈冲外,还可以产生形状类似于各种辐射探测器(闪烁计数器、正比计数器、电离室等)所产生的脈冲信号。 输出信号能够随时间均匀分布或按统计分布。 脈冲的延续时间,重复频率,双脈冲之间的时间间隔,可以在很大的范围内改变。

A practical means is presented for the design of a coherent Integrating Filter (GIF) covering the whole doppler frequency range with a single channel, as it is much simpler than the usual way of implementing the coherent integration by a large number of parallel channels each matched at a different doppler frequency, therefore it is easier to implement and superior than the parallel matched filters scheme.

A practical means is presented for the design of a coherent Integrating Filter (GIF) covering the whole doppler frequency range with a single channel, as it is much simpler than the usual way of implementing the coherent integration by a large number of parallel channels each matched at a different doppler frequency, therefore it is easier to implement and superior than the parallel matched filters scheme. The paper has analyzed the principle of operation of the GIF, pointed out that it is equivalent to a set of high frequency sweeping comb filters but with no sweeping loss. GIF implements the optimum receiver by inclined cutting the Woodward's "uncertainty function" as contrast with the ax-is parallel cutting implemented by the matched filters.The block diagram of a radar system with GIF is presented in the last section and the choice of some system parameters is explained.

提出一个具有能在未知多卜勒频移情况下不需分路的相参积累器,它比一般分路方案可以简单得多。因此在从噪声中发现微弱信号的角度来看,优于其他曾提出过的任何积累方案。文中分析了这种积累器的作用原理,提出了利用这种积累器组成的积累滤波器如何能对脉冲串高频信号获得最佳信噪比,并用模糊度函数的概念说明了这种积累滤波器的实质,指出它比脉冲串匹配滤波器更优越和具有较大的实现可能性。最后还讨论了利用这种设备进行雷达站设计的要点和某些工作参数的选择与考虑。
